AUNIC to APNIC migration
Transfer of AUNIC network records
During May 2001, all network records within the AUNIC database were moved to the APNIC database. These records were removed from AUNIC on July 1. The IP range affected is:
203.0.0.0 to 203.63.255.255
Now this transfer is complete, the AUNIC database is no longer authoritative for IP addresses within the above range.
Policy changes that affect former AUNIC ranges
Recovery of unused historical IP addresses
A significant amount of historical address space registered in the APNIC Whois Database is not announced to the global routing table. To recover these globally unrouted resources and place them back in the free pool for reallocation to other networks, APNIC will contact networks responsible for historical address space in the APNIC region that has not been globally routed since 1 January 1998. For more information see:
- Section 5 of the Policies for historical Internet resources in the APNIC Whois Database
- Guide to the recovery of unused address space
Transferring IP addresses to another organisation
To transfer historical Internic or AUNIC resources to a current APNIC account holder, please see:
- Section 4 of the Policies for historical Internet resources in the APNIC Whois Database
- Guide to the transfer of historical Internet resources
Updating information in the APNIC Whois Database
To ensure the integrity of information in the APNIC Whois Database, APNIC will not update historical information in the APNIC Whois Database until the resource holder can prove the organisation's right to the resources and has a formal agreement with APNIC as a member or non-member account holder. For more information, please see:
- Section 6 of the Policies for historical Internet resources in the APNIC Whois Database
- Guide to the maintenance of historical Internet resources
Change to person objects
As part of this transfer, all person objects referenced by the above network objects were copied to the APNIC database. Please note the objects in the range above were not deleted from the AUNIC database. Where possible, the same initials and numbers were used for the nic-handle, substituting '-AP' for '-AU'. Where doing this conflicted with an existing APNIC person object, the first available nic-handle was used. For example, for the AUNIC nic-handle 'XY123-AU', two things could happen:
'XY123-AP' does not already exist in the APNIC database and is transferred as is, or
if 'XY123-AP' already exists in the APNIC database, the next available nic-handle is be chosen - 'XY124-AP'.
A letter has been sent to the e-mail addresses of all person objects affected by this change, together with information on how to use the APNIC database (for example, user authentication for changes, how to manage reverse delegations etc).
APNIC membership
As of 3 December 2001 APNIC now has a new membership category that caters for networks responsible for the smaller address blocks allocated within the former AUNIC range. Networks with up to and including /22 are now eligible to become Very small members for an annual fee of AU$1,584. For details on what APNIC membership can offer your organisation, please see APNIC membership information.
